This invention relates to shoe machinery,

and particularly to an improved machine for cutting or skiving the heelend of-soles, the object being to provide a machine which willaccurately skive the heel end of a sole, whereby it will be properlyshaped.

Anotherohject of the invention is to provide a skiving machine forcutting the sides and ends of theheel portion of-the sole of a shoe,whereby this heelportion. will prop- I erly fit a wooden heel orother'heel of a shoe when the shoe is being completed.

r A further object, more'specifically is to provide a skiving machinefor cutting the heel end of a sole in such a way that both the sides andoneend are properly chamfered.

to properly receive the heel. This is particularly true in respect towooden heels and in the present invention a machine has beenprovided-which at one operation slzives the heel portion of the sole ina substantially perfect manner. This skiving results in chanifering theedges of the heel portion so that the heel portion will fit properlyagainst the wood heel. lVhen this operation is done by hand it IS quiteoften done inaccurately and poorly. so that certain adjustments andcompensating additions must be made to secure a proper fit. In a machineembodying the invention the heel portion is always properly cut andconsequently saves much time in the manufacture of the shoe. As shown inFigure 2, the machine embodying the invention is provided with a basestructure 1 which may be mounted on any suitable support 2. Arranged onthe base 1 is a platform 12 held in place in any desired manner, andstraddling this platform is a yoke 3 having a slideway a for purposeshereinafter fully set forth. A pair of guideways 5 is also bolted orotherwise secured to base 1 and each guideway 5 provided with anupstanding bracket 6. A pin 7 extends through the brackets 6 a 1dthrough a lever 8 forpivotally mounting this lever, as clearly shown inFigure 2. Lever 8 at one end carries a con tact roller 9 bearing againstthe cam 10 and at the oppesite end is pivotally connected at 1! tosliding block 12 arranged in the head 3' oi olte 3. screw is connectedwith the block 12 4 head plate 1+1- so as to support the spring 15acting'on the screw head 16. By reason of this arrangement spring 15 hasatendency to keep the parts substantially in the position shown inFigure 2 with the knife 17 elevated. \Vheneverthe operating or large end18 of cam 10 is acting on the roller 9 block 12 is forced downwardly sothat the knife 17 will be moved in the position shown in Figures 5 and7, whereby the cut or discarded portion CIA ' ders V in guide 5 but 19of sole 520 is severed from the body of the sole. As shown in Figures 1and 2 the solo is placed on the support or platform 12' with the troutor-toe end against the :rdjust able abutment or stop 21, whereby "he endol portion of the solo will extend to Immediately after the rollerpasses the for- V ward end of the heel portion 28, us shown in Figure 5,knife 1? will move downwardly to ou off the portion 19 as it cuts theshoultion'oi the skived heel portion 28, as shown in F gure 8, thuspernntting the sole 20 to be manually removed and s new one substivtuted. After the new one his been substituted the some operation isperformed and so on as long as the machine is in operation.

As shown in Figure 6, the die 2-3 is provided 'withroughened portions 31which prevent the sole from slipping during the cutting oporation. Theroller 24 by reason of its mounting has a very limited or slightresilient ac,- tioh and consequently can be readily forced overthe end22 end then moved, as shown in, Figure 3, for depressing the center ofthe sole. As shown in Flgures l and 2- the roller 24 is mounted on ayoke 32 which is screwed, riveted or otherwise rigidly secured to esliding .plete 33 slidably mounted in the guide or runwaysS. The plate33 iits rather snugly allows a very slight resilient ction in order thatthe roller 24 may pass over the end; 22 also curries the knife 27, whichis Yrernovably' secured in pliice by screws; A block 34 is pivotellyconnected with-the plate 33 by pinBS si-iid' bloclc halving a threadedbore 36 for receivingone end of the screw 37, the opposite end beingthreaded into'the enlarge.-
